Pollen count Charter Oak residents check each morning
The Charter Oak pollen count today is 28 (Low). The main driver is Ragweed, with weed pollen at 36 today. The full split is tree pollen 0.6, grass pollen 0.6, weed pollen 36. The sections below break that headline number down by plant, by day and by what the band means in practice. Pollen Atlas updated this count on Saturday, November 7, 2026.
A Low band on the Pollen Atlas index means the Total Pollen Index has stayed in the lower part of the 0–100 scale. Readings in this band are built from low individual category values rather than from one large spike, and the category split above matters more than the headline number: a low total can still contain one category, such as weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Charter Oak page.
Fall is ragweed season across most of the United States: ragweed plants release pollen from late summer into autumn, and weed pollen is typically the last major outdoor pollen category to fade as the weather cools. That pattern is why an autumn total is so often weed-led even when the headline number is low — tree and grass pollen have usually receded by then, leaving weed pollen, and on damp days mold, to make up most of what the index records. In the Plains and around the Great Lakes, ragweed is a familiar late-season plant of open ground, field edges and disturbed soil, which is why it so often leads inland autumn readings.

Pollen by type in Charter Oak
What is driving Charter Oak’s pollen today
The shape of today’s 28 (Low) is set by weed pollen at 36 (Low on its own scale) — about 97% of the four category readings added together, 35.4 points clear of the next category, tree pollen at 0.6. A weed-led total is the classic late-year shape: tree and grass pollen have usually receded, leaving weed pollen — and on damp days mold — to make up most of what the index records. Weed pollen leading in November runs against the usual calendar — the Iowa weed chapter runs August to October — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.
Plant-level detail is not in today’s feed for Charter Oak, so the drivers have to be read from the category split above. The Iowa guide’s account of Iowa names ragweed, the state’s dominant allergen, over a maple, oak and hickory spring — the pollens behind readings of this shape in this state — and the split shows how much of today’s total each category is actually carrying.
Across the five-day window the Total Pollen Index runs from 27 to 28, never changing band. Today’s 28 sits 1 point above the window’s average of 27.2 — a steady window, in which one day reads much like the next.

Charter Oak pollen through the year
The Charter Oak pollen year runs in chapters, set by the Midwest & Great Lakes pattern and the Iowa calendar. Trees come first: trees run from March into May, later near the big lakes. Grasses take the middle of the year: grasses hold from May through July. Weeds close it out: ragweed builds from mid-August, peaks in September, and ends at the first frost. Mold builds through the humid summer and fills the gaps between chapters.
The Iowa allergy season guide names ragweed, the state’s dominant allergen, over a maple, oak and hickory spring. Des Moines finished in the top ten of the Asthma and Allergy Foundation of America’s 2024 Allergy Capitals list, reflecting that complete, high-volume calendar. The river valleys are the tree reservoirs: oak-hickory floodplain woodland along the Des Moines, Cedar, Iowa and Mississippi rivers feeds the spring season through valley towns.
November falls between the main chapters of the Iowa pollen year — the tail of one and the approach of the next — so the calendar alone explains little today, and the modelled split above carries the story. Between them, the three chapters cover 8 months of the Iowa year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Iowa allergy season guide.
How to read this index
Pollen Atlas reports the Charter Oak pollen count on a Total Pollen Index from 0 to 100, built from separate tree, grass and weed readings. The total is a summary, not an average of the three: a single strong category can lift it, and three quiet categories can hold it down even in a month when Charter Oak, IA pollen is usually more active. Index values are a modelled pollen risk index computed by Pollen Atlas from open weather, vegetation and phenology data, calibrated against CDC/NAB season data, with plant detail by the Google Pollen API. The index is a modelled 0–100 scale, not a measured count, and figures update through the day, so a morning and an evening visit to this page can legitimately show different numbers.
